8-bit REAL TIME CLOCK MODULE
RTC-64611/64613
• Builtin crystal unit allows adjustment-free efficient operation.
• 8-bit data bus and high speed access (85 nsec. max.).
• Provided with the same interface as S-RAM and battery backup function.
• Interruption of alarm of sec. to day and day of week and carry interruption.
• Reference signal selectable in a range of 1 Hz to 64 Hz (binary).
• Leap year automatically adjustable (gregorian calendar).
• With 1 Hz output terminal.
• Provided with START/STOP, 30 second adjust function.
• RTC-64613 uses a similar mounting method to that of a normal SMD IC.
